Small bend radius optical fiber

Edit: Date: 2019-01-13

Fiber bending loss is due to the conduction -mode optical fiber bent portion of the optical fiber into a radiation mode caused. It is the bend radius of the fiber exponential relationship, the larger bending radius, bending loss is smaller.

Now commonly used in G652 fiber minimum bend radius is 30MM. This year began as a small application G657 bend radius optical fiber, respectively G657A1, G657A2, G657B3. G657A1 minimum bend radius is 10MM, G657A2 fiber is 7.5MM, G657B3 fiber is 5MM. Small bending optical fiber has a smaller than normal bending radius, also known as anti-bending optical fibers, mainly used in FTTX, FTTH, and suitable for indoor use of a narrow space, or the corner.
